My invention relates to electricity meters which areprovided with covers. held in place by rods carried by the. meter bases, these rods projecting forwardly through the covers and having nuts threaded thereon which hold. the covers in place I provide an improved sealing means at the apertures in the covers through which said rods pass. In carrying'out my invention, I equip the nuts and covers with engaging male and fe male portions. To this end I preferably interpose a washer betweenthe inner end of the nut upon each' rodjthat project'sthrough the front wall ofi'th'e; meter cover. The washer and cover desirably have enga giijig maleand femaleformations-as the nut and washer preferably have also, whereby access of tampering" wires to the rotating element of the meter enclosed by the cover for checking or stopping the meter is effectively guarded against.

I will explain my inventionmore fully by reference to the accompanying drawing in which Fig. 1 is a sectional view of one construction; Fig. 2 is an enlargement of a part of the structure as it appears in Fig. 1; Fig. 3 is a perspective view of parts shown in Fig. 2, but in separated relation; and Fig. 4 is a sectional view of another construction, which is preferred.

The meter base in the meter shown is inclusive of a plate 1 formed with a forwardly projecting wall 9. toconstitute a chamber. The motive element of the meter is suitably mounted upon the rear of a partition wall 3. The electro-magnets of the motive element of the meter, of which the current magnet 4; isshown, are upon the rear side of the wall 3, being surrounded by the wall 2 and enclosed within the chamber defined by said wall. The upright meter spindle 5 is positioned by bearings which are carriedby the wall 3 upon the front thereof, as is understood by those familiar with the art. The spindle carries a non-magnetic.metallic armature disc 6 which extends into inductive relation with the'magnets. 1

The cover 7 commonly of glass, is seated upon the front portion of the wall 2, a seal ing gasket 8 being interposed between the cover and said wall. The cover is held in position by two rods 9 which are carried by the base and project forwardly therefrom through the cover-Q Two nuts 10 are threaded upon; these rods andpress uponthe cover to'h'old'it upon its seat.

A washer is employed"betweeneach nut and the front of the cover Each washer" has it body portion 11 which'is directly on gaged bythe inner face-of;ihe correspond} iug nut. The cover and each washer have engaging male and female formations as do each washer and nut. bodiment of the invention the cover is formed with a-boss12 surrounding each openingthrough which aJrod 9passes and each'washer is formedwith' a skirt portion 13 extending towartbth'e cover and receiving" the correspondingboss. Each washer also has a sleeve continuation 14 extending away from the cover andtlirough "which the con-e s].i0ndii-i bore of'thje cori riding nut enlarged as indicated at 15; and receives" the corresponding sleeve let that is preferably in sliding relation with the nut. The structure of Fig. 4 is obvious. In this structure, a felt washer 16 is also shown.

a It is obviously extremely difiicult, if not impossible, to fish a wire through the front of the cover into braking contact with the rotating element of the meter.

Changes may be made without from the invention.

Havingthus described my invention, I claim:

1. The combination with an electricity meter; of a supporting base therefore; a cover for the meter and engaging said base; a rod projecting from the base and passing through an opening formed in the cover; a sealing nut screwed upon the outer end of said. rod; and a washer interposed between the nut and cover and having a skirt portion extending. toward the cover and receiving a boss that is formed on said cover around said opening, said washer also having a departing sleeve continuation extending away from said cover and through which said rod passes, the. inner end of the bore of the nut bengenlarged and receiving said sleeve upon the washer.

2. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a rod projecting from the base and passing In the preferred em rod 9 passes. llheiiiner end of the through an opening formed in the cover; a sealing nut screwed upon the outer end of said rod; and a washer interposed between the nut and cover and having a sleeve con tinuation extending away from said cover and through which-the rod passes, the inner end of the bore of the nut being enlarged and receiving said sleeve upon the washer.

3. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a rod projecting from the base and passing through an opening formed in the cover;

a sealing nut screwed upon the outer end of said rod; and a 'asher interposed betweensthe nut and cover and having a skirt portion extending toward the cover and re-- ceiving a boss that is formed on said cover around said opening.

4-. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a rod projecting from the base and passing through an opening formed in the cover; a sealing nut screwed upon the outer end of said rod; and a washer interposed between the nut and cover, said cover and washer having engaging male and female formations surrounding said opening, said Washer and nut also having engaging male and female formations surrounding said rod.

5. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a. rod projecting from the base and passing throughan opening formed in the cover; a sealing nut screwed upon the outer end of said rod; and a washer interposed between the nut and cover, said nut and washer having engaging male and female formations surrounding said rod.

6. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a rod projecting from the base and passing through an opening formed in the cover; a sealing nut screwed upon the outer end of said rod; and a washer interposed between the nut and cover, said cover and washer having engaging male and female formations surrounding said opening.

7. The combination with an electricity meter; of a supporting base therefor; a cover for the meter and engaging said base; a rod projecting from the base and passing through an opening formed in the cover; a sealing nut screwed upon the outer end of said rod, said cover having a boss surrounding the opening through which said rod passes; and a skirted member between said nut and cover and surrounding said boss.

In witness whereof, I hereunto subscribe my name.
